Book Description

Recent catastrophic blackouts have exposed major vulnerabilities in the existing generation, transmission, and distribution systems of transformers widely used for energy transfer, measurement, protection, and signal coupling. As a result, the reliability of the entire power system is now uncertain, and many blame severe underinvestment, aging technology, and a conservative approach to innovation.

Composed of contributions from noted industry experts around the world, Transformers: Analysis, Design, and Measurement offers invaluable information to help designers and users overcome these and other challenges associated with the design, construction, application, and analysis of transformers. This book is divided into three sections to address contemporary economic, design, diagnostic, and maintenance aspects associated with power, instrument, and high-frequency transformers.

Topics covered include:

  • Design considerations

  • Capability to withstand short circuits

  • Insulation problems

  • Stray losses, screening, and local excessive heating hazard

  • Shell type and superconducting transformers

  • Links between design and maintenance

  • Component-related diagnostics and reliability

  • Economics of life-cycle cost, design review, and risk-management methods

  • Parameter measurement and prediction

This book is an essential tool for understanding and implementing solutions that will ensure improvements in the development, maintenance, and life-cycle management of optimized transformers. This will lead to enhanced safety and reliability and lower costs for the electrical supply. Illustrating the need for close cooperation between users and manufacturers of transformers, this book outlines ways to achieve man

Xose M. Lopez-Fernandez received his MSc in electrical engineering and his European Ph.D (with first-class honors) in electrical engineering from Vigo University, Spain, in 1992 and 1997, respectively. He is currently a professor in the Department of Electrical Engineering at that school and was a visiting professor at the University of Artois, Bethune, France. Professor Lopez-Fernandez is the founder and general chairman of the International Advanced Research Workshop on Transformers (ARWtr). He is currently being entrusted with the responsibility of leading research projects for Spanish and Portuguese utilities and power transformer manufacturers. His research interests include the design aspects of electrical machines. Dr. Lopez-Fernandez received the Alfons Hoffmann’s Medal from the Polish Power Engineering Society in 2004. He is a member of the IEEE-PES Transformers Committee as well as CIGRE.

H. Bulent Ertan received his BS and MS in electrical and electronics engineering (EEE) in 1971 and 1973, respectively, from the Middle East Technical University (METU) in Ankara, Turkey. He also received his Ph.D from the University of Leeds, England, in 1977. He then joined METU as a staff member in that same year. Professor Ertan is currently a staff member of the Department of Electrical and Electronics Engineering at METU. His research interest is in the area of electrical machine design and electrical drives, and he has consulted for a number of companies manufacturing electrical motors and drives in Turkey. He has directed more than 20 industry-financed research projects and many other projects financed by the Turkish Scientific and Technological Research Institute (TUBITAK). He has served as the assistant director of TUBITAK Information Technologies and Electronics Research Institute since 1999 and led the Intelligent Energy Conversion Systems Research Group at TUBITAK-SPACE Institute for 8 years.
